l SELF-AD JUSTING BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented .Tune 16, 1908.

Application filed October 3, 1907. Serial No. 395,741.

To all whom it may concern.'

Be it known that I, HENRY CHARLESTON HARNESS, a citizen of' the UnitedStates, residing at New Rochelle, in the county of Vestchester and Stateof New York, have invented certain new and useful Improvements inSelf-Adj usting Bottle-Closures g and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanyi ing drawings, and to theletters and figures of reference marked thereon, which form a tz part ofthis specification.

My invention relates to a self adjusting stopper and closure forbottles, jars and the like, and has for its object to provide a deviceof this class which will allow the pressure on the inside of the vesselto increase without bursting the vessel.

A further object of my invention is to provide a cap or closure whichwill rise to suit the pressure within the vessel and at the same timekeep the vessel closed.

Vith these objects in view my invention consists in the novelconstruction of the bottle stopper or closure and in certaincombinations ol' parts all of which will be first fully described andafterwards specically pointed out in the appended claims.

Referring to the accompanying drawing: Figure 1 is a vertical sectionalview taken through a jar illustrating my stopper or closure appliedthereto. Fig. 2 is a top plan view of the same. Fig. 3 is a top planview showing the cap of stopper or closure removed. Fig. 4 is a top p anview of the removable barrel portion of the device. Fig. 5 is a bottomplan view of the removable barrel portion of the device. Fig. 6 is aplan view of the cap. Fig. 7 is a side elevation of the cap.

Like numerals of reference indicate the same parts throughout theseveral figures in which l- 1 indicates the bottle, jar or vessel, and 2indicates the self adjusting stopper or closure, said stop er or closurecomprising a permarient barre portion 3 and removable barrel portion 4,a cap 5 and washer 6, all of the parts exce t the washer 6 being made ofsuitable meta while the said washer 6 is preferily made of card-board orsimilar material.

`he`permanent barrel portion 3 is con- \as shown in Fig. 1 having anupper portion 7 which is turned over a bead S of the bottle, jar orvessel in order to secure the permanent barrel portion within the 'neckof the bottle, jar or vessel. The barrel portion 3 comprises a verticalwall 9 fitting the neck of the vessel snugly, a bottom 10 and a verticalwall 11 extending upwardly within the wall 9, the barrel portion 3 thusforming a receptacle.

Within the receptacle formed and between the vertical walls 9 Vand 11 isthe removable barrel portion 4 which, as shown in Fig. 1, comprises avertical wall 12, said wall terminating in two flanges 13 as shown inFigs. 1 and 5, while the upper end of the wall 12 is provided with anannular flange 14, said annular flange 14 being provided with preferablytwo hooks or lugs 15 as shown in Figs. 1 and 4. Referring again to thepermanent barrel portion 3 it will be seen that on the upper end of theouter wall 9 are two inwardly extending iianges 16 as shown in Figs. 1and 3.

Referring to Figs. 2 and 6 it will be seen that the cap 5 is providedwith two notches 17 andtwo inclined planes 18 shown also in Fig. 7 whilea central wall 19 is also provided for turning the cap. If desired, asmall chain 2O having one end secured to the cap and the other endsecured to one of the lugs 15 can be employed for preventing loss of thecap.

Having thus fully described my invention its operation is as follows:The permanent barrel portion 3 is inserted in the neck of the vessel andsecured thereto as shown in Fig. 1 the removable barrel portion 4 isthen inserted within the permanent barrel portion 3, the flanges 13 onthe bottom of the removable barrel portion 4 entering between thefianges 16 on the top of the permanent barrel portion 3 as shown inFigs. 4 and 5. A coil spring 21 is then inserted within the permanentbarrel portion 3 the lower end of the spring resting against the flanges13 on thc removable barre portion 4, while the upper portion of thespring 21 engages the flanges 16 at the top of the permanent barrelportion 3. The washer 6 is then placed upon the top of the removablebarrel portion 4 and the cap 5 is placed upon the washer, the notches 17in said cap registering with the lugs 15 on the said removable barrelportion 4. The cap is then rotated by means of the vertical wall 19until the inclined planes 18 on the cap pass under the lugs 15 on theremovable barrel portion 4, thus holding the cap firmly in position onthe removable barrel portion 4. The cap or closure being thus held inposition upon the removable barrel portion 4. and the removable barrelportion 4 being yieldingly held within the permanent barrel portion 3 bymeans of the coil spring 21 it is at once evident that the removablebarrel portion 4 and cap 5 will rise to any pressure within the vesselthus adjusting the closure to the pressure and preventing bursting ofthe vessel, while at the same time closing the contents therein.

Having thus fully described my invention what I claim as new and desireto secure by Letters latent` of the United States is,-

1. A self adjusting closure for bottles, jars and the like comprising apermanent barrel portion comprising two vertical walls arranged withinthe neck of the bottle, jar or the like7 a removable barrel portioncomprising a vertical wall arranged within the said permanent barrelportion, a coil spring interposed between one of the walls of thepermanent barrel portion and the said vertical wall of the removablebarrel portion, a washer on said removable barrel ortion, a cap on saidwasher and interlocking means between said cap and said removable barrelportion for securely holding the cap in position, substantially asdescribed. v

2. A self adjusting closure for bottles, jars and the like comprising apermanent barrel portion arranged within the neck of the bottle, j ar orthe like, a removable barrel portion comprising a vertical wall arrangedwithin the said permanent barrel portion, a s ring in engagement witheach of said barre portions for resiliently holding the removable barrelportion within the said permanent barrel portion, and means for closingthe said removable barrel portion, substantially as described. f

3. A self adjusting closure for bottles, jars and the like comprising apermanentv portion arranged within the neck of the bottle, jar or thelike, a removable port-ion inserted within the said permanent portionand resiliently held therein, and a cap or closure for interlockingengagement with the said removable portion for closing the same,substantially as described.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
